Abstract
Description
- The present invention relates to an improvement of I/O units and a distribution board for numerical control apparatus, adapted to transfer of signals between a numerical control apparatus and a machine side controlled by means of the numerical control apparatus.
- In order to drive a machine tool by means of a numerical control apparatus, it is necessary to transfer signals between the numerical control apparatus and the machine side. This signal transfer is carried out by means of wires, such as cables, that are connected between the numerical control apparatus and input/output terminals on the machine side. In general, the connection between the numerical control apparatus and the machine side varies depending on various conditions, such as the type and scale of a machine in a system of the machine side. Conventionally, therefore, a distribution board and an I/O unit are employed for facilitating the connections with cables and the like to the machine-side system. In such a case, the distribution board is manufactured for each machine so that it can fit the machine to be controlled by means of the numerical control apparatus, while, for the I/O unit, commonly available is used.
- FIG. 3 is a block diagram for illustrating the connection between a conventional numerical control apparatus and a machine side. Referring to FIG. 3, an I/
O unit 24 and adistribution board 23 are arranged between anumerical control apparatus 21 and amachine side 22, and are connected by means ofcables distribution board 23 is set corresponding to the machine-side system 22. - The I/O connection between the conventional numerical control apparatus and the machine side has problems in terms of operating efficiency and productivity.
- In making the I/O connection between the conventional numerical control apparatus and the machine side, the
distribution board 23 is set singly corresponding to the system of themachine side 22, as shown in FIG. 3, for example. Moreover, on the machine side of the I/O unit 24, the I/O unit 24 and themachine side 22 require at least two cables (wires 32 and wires 33 and 34) between themselves and thedistribution board 23. Accordingly, thedistribution board 23 must be set corresponding to the machine-side system, and the number of cables for the connection to thedistribution board 23 has to be increased, so that it is difficult to improve the operating efficiency and productivity of the distribution board. - In the case where the volume of signals between the
numerical control apparatus 21 and themachine side 22 is increased, as shown in FIG. 4, it becomes necessary to use two distribution boards (23a and 23b) and additional I/O units distribution boards machine side 22, and the number of cables for the connection between them increases accordingly. - By manufacturing the I/O units of the numerical control apparatus adapting to the
machine side 22, the distribution boards themselves may be omitted to prevent the increase in the number of cables attributable to the increase of the distribution boards. In this case, however, an I/O unit must be manufactured for each of different machine tools. In general, however, an I/O unit requires a communication circuit, which transmits and receives signals to and from the body of the numerical control apparatus itself, and a transmitter-receiver circuit, which transmits and receives signals to and from the machine side. Thus, providing these circuits for each of different machine tools entails high manufacturing and operating costs. - The object of the present invention is to provide I/O units and a distribution board for numerical control apparatus, the I/O units and the distribution board being formed integrally without using wires between the I/O units and the distribution board, so that packaging spaces and the number of wires are reduced.
- In order to achieve the above object, in an I/O unit and a distribution board for numerical control apparatus according to the present invention, the distribution board has wirings manufactured in conformity to a machine-side system controlled by means of a numerical control apparatus and is provided with connectors detachably mounting a plurality of I/O units each including transmitter-receiver means, and the I/O units are designed so as to be able to be attached to the connectors of said distribution board. When the I/O units are attached individually to one or more of the connectors on the distribution board, the attached I/O units and the wires are connected, whereby input/output connection between the numerical control apparatus and the machine side is accomplished.
- As described above, according to the present, invention, the I/O units and the distribution board are formed integrally without using wires between the I/O units and the distribution board, so that packaging spaces and the number of wires are reduced, resulting in improvement in costs and operating efficiency.

connectors distribution board 3 are fitted with the I/O units O unit 4a is provided with acommunication circuit 5, an input/output signal control circuit 6 (illustrated as a control circuit 6), and a transmitter-receiver circuit 7a, while other I/O units receiver circuits communication circuit 5 of the I/O unit 4a enables thedistribution board 3 and the numerical control apparatus 1 to communicate with each other through thecable 13 and aconnector 8. The input/outputsignal control circuit 6 directly controls the transmitter-receiver circuit 7a of the I/O unit 4a and controls the respective transmitter-receiver circuits O units connectors wiring 14, etc., thereby regulating the transmission and reception operations of the transmitter-receiver circuits. These transmitter-receiver circuits machine side 2 through thewires 15 and thecables - Thus, only the I/
O unit 4a is provided with thecommunication circuit 5 and the input/outputsignal control circuit 6, while other additional I/O units receiver circuits - Regarding the transmitting and receiving capacities of the respective transmitter-
receiver circuits O units 4, if it is assumed that the numbers of connectable points on the input side and output side are 16 and 6, respectively, for example, then the numbers of connectable points available on the input side and output side of the four I/O units - If a machine tool controlled by the numerical control apparatus requires 60 points for the input side and 30 points for the output side, in this case, numerical control can be carried out through connections for transmission and reception with this arrangement of the
distribution board 3 that includes the I/O units - In the case where the machine tool controlled by means of the numerical control apparatus requires more input and output points, an I/O unit 4e is additionally attached to the
